The pathologist's role in evaluating adrenal tumors is multifaceted, serving as the definitive bridge between advanced imaging and personalized treatment plans. While radiologists identify the presence of a mass, the pathologist determines its origin, behavior, and potential for malignancy through microscopic and molecular analysis. 

  1. Establishing the Origin and Nature of the Tumor
    The pathologist first confirms that a tumor is truly of adrenal origin, as a subset of masses discovered in the adrenal gland is actually metastases from other sites, like the lung or  breast. 
    Adrenocortical vs. Medullary: They distinguish tumors arising from the adrenal cortex (adenomas or carcinomas) from those arising from the adrenal medulla (pheochromocytomas).
    Specialized Staining: Special markers are available to confirm tumor origin and perform functional analysis as needed.
  2. Differentiating Benign from Malignant Lesions
    This is perhaps the pathologist's most critical task, as the appearance on a scan often cannot definitively prove cancer. 
    Multiple Scoring Systems: Pathologists use a multi-parametric scoring system to evaluate specific histological criteria, including nuclear grade, mitotic rate, reticulin framework, and  evidence of invasion into blood vessels or the tumor capsule. A high score typically indicates adrenocortical carcinoma (ACC) and requires careful clinical consideration.
  3. Providing Prognostic and Therapeutic Information
    Beyond a diagnosis, the pathologist provides data that directly dictates the intensity of follow-up care and the selection of therapies, such as Ki-67 proliferation index for ACC and  SDHB immunohistochemical stain for paraganglioma/pheochromocytoma.
  4. Guiding Multidisciplinary Care
    The pathologist serves as a core member of a multidisciplinary tumor board, collaborating with surgeons, oncologists, and endocrinologists who read our diagnoses and analyses to patients and generally treat them based on standardized protocols for these diagnoses. We are also always available to discuss our findings directly with the patient.
